RAZOR-SHARPENER.

Specification of Letters Patent.

Patented Aug. 11, 1914:.

Application filed November 9, 1912. Serial No. 730,337.

To all whom it may concern:

Be it known that I, JACOB A. Knnss, a citizen of the United States, residing at Canton, in the county of Stark and State of Ohio, have invented a new and useful Razor- Sharpener, of which the following is a specification.

My invention relates to improvements in means for stropping the blades of razors and the like, the blade being supported by an oscillating blade holder actuated by a reciprocating stropper.

The objects of the invention are to generally improve devices of the character men tioned and to provide'a tho-roughly eflicient razor sharpener by an appropriate combina tion of elements hereinafter described and distinctively pointed out in the appended claims. These objects, together with other objects apparent to those skilled in the art, may be attained by the construction illustrated in the accompanying drawings, al though the invention may be embodied in other forms, the construction illustrated being chosen by way of example.

In the drawings Figure 1 is a perspective view of the razor sharpener embodying my invention, the blade of the razor being shown arranged therein and parts being broken away. Fig. 2 is a perspective view of the sharpener frame, the strop and blade holder being omitted. Fig. 3 is a longitudinal, vertical, sectional view through a razor sharpener embodying my invention. Fig. 4 is a top View. Fig. 5 is a horizontal sec- 7 tional view on the line 5-5 of Fig. 3 showing the parts in the position assumed when the strop is moving in one direction. Fig. 6 is a similar View on the line 6--6 of Fig. 3 showing the parts in the position assumed 7 when the strop is moving in the other direction. Fig. 7 is a perspective view of the blade holder. Fig. 8 is a vertical sectional view of the same. Fig. 9 is a perspective view of the blade-holder-actuating roll. Fig. 10 is a perspective view of the bladeholder-returning spring. 1

Throughout the several views similar reference numerals indicate similar parts.

More specifically describing the construction disclosed in said drawings the numeral 1 indicates the upper frame plate, the numeral 2 the lower frame plate, said plates being connected by the integral yoke 3 to which is pivotally connected the attaching ring 4: by which the device may be fastened to a hook or other stationary support. The plates 1 and 2 and the yoke 8 are preferably stamped from a single piece of sheet metal of sufficient thickness to insure strength and rigidity. The said plates 1 and 2 are, in general, parallelly disposed, the lower plate 2 being considerably longer than the upper plate 1. V

The upper, plate 1 is provided with the razor opening 5, the rear end of which opening is somewhat spaced from the yoke 3. By reason of said opening 5 the upper plate 1 is thus provided with the two upper side pieces 6 and the upper front piece 7. In a somewhat similar manner the lower plate is provided with an opening 8, the rear end of which is spaced farther from the yoke 3 than the rear end of the opening 5, said opening 8 producing in the lower plate the lower side pieces 9 and the lower front piece 10.

For the purpose of fixedly connecting the front ends of the plates 1 and 2 the two connecting and spacing bars 11 are provided, each of said bars being connected to the upper front piece 7 and to the lower front piece 10 in a fixed, permanent manner. It will be noted that said bars 11 assume an inclined position with reference to the normally vertical yoke 3.

At the rear ends of the openings 5 and 8 are the upper and lower blade-holderattaching ears l2 and 13 respectively. These ears are formed integrally with the plates 1 and 2 and are bent upwardly at an angle with reference to said plates, said ears, however, being parallel with each other and the lower ear 18 being considerably in advance of the upper ear 12.

The blade holder is preferably formed from a single sheet of spring steel and comprises the back 14 and the integral clamping flanges 15 and 16, which converge toward their free edges opposite the back 1 1 and are adapted to clamp the blade of a razor such as shown at 17 in the drawings, permitting the cutting edge of the razor to protrude beyond the free edges of said flanges. The flange 15 is provided with an integral stop lug 18 at the bottom end thereof, which lug is bent over across the lower end of the flange 16 to form a stop to prevent the point of the razor blade from protruding beyond the lower end of the holder. Formed integrally with the lower end of the back leis the lower holder arm 19 pro vided with an aperture and with a pair of upwardly turned, inwardly directed spring holding lugs 21 for the purpose herelnafter more fully disclosed. At the upper end of said back the integral upper holder arm 22 is provided, said arm having an aperture 23 intermediate its ends, and the free end of said arm provided with an integral, inverted-cup-shaped head 24, the outer edges of which are rounded to produce abearing surface. Extending from the car 12 to the car 13 is the blade-holder-attaching bar 25; said bar passing through the aper-' tures 20 and 23 in the lower and upper holder arms 19 and 20 respectively. In this manner the razor holder is pivotally mounted in the frame in inclined position corre-' sponding substantially to the inclination of the bars 11.

Between-the flanges 15. and 16: and connected to the back 1 1 are the upper and lower blade pressing springs 26 and 27.

The spring 27 is connected'to the back 14: by a ingle rivet at its lower end, the upper end of said spring 27 being free from said back and normally spaced therefrom. The upper-spring 26 is connected at its upper end to the back 14: and its lower free end over-lies the spring 27, as clearly illustrated in Figs. 3 and 8. The purpose of these springs i to hold the bladeof a razor in proper position between the flanges 15 and 16 so that the cutting edge thereof will protrude from the holder and be held inproper position. x

The blade-holder-returning spring is preferably formedof wire and of the formillusnected to the upper and lower plates 1and2 tra'ted-in Fig. 10 comprising a coil 28 of one and one-half turns and the integralfree ends 29. The coil 28 is arranged around'the bar 25' and the. ends 29 are brought under the spring holding lugs 21, the said spring being thus held down'in place adjacent the holder arm 19. Preferably stamped from the lower frame plate '2 are two. raised, spaced, inwardly turned lugs 30 adapted toloosely engage the ends 29 to prevent out-ward, side movement of said ends when the blade holder is oscillated.

The blade holder actuating roll i preferablystamped from sheet. metal and com prises the incomplete hollow cylinder 31 having the spaced edges 32, integral portionsofi the metal being bent. over at the endsto form the end flanges 33 provided with apertures 34 adapted to rotatably re-' ceive the rollattaching-rod 35, which is conin position parallel to the yoke 3. The edges 32 are'frontwardly disposed and receive between them the flange 24 at the free end of the upper arm 22 of the blade holder.

It will be thus apparent that when the bladeholder-actuatingroll is rotated inv one direc tlon-the blade holderwill be oscillated by rotary movement about the 25 in the op V p osite direction, and vice versa. .As the blade holder is'oscillated to one side or the other the returning'spring on the lower arm 19 will press firmly against one or other of the lugs 3 ).and will tend to return the holder to the intermediate position illustrated in" .The' strop 36 is provided with suitable handle 37 at its two free ends ande'xtends' around 7 the bladehold'er-actuating roll, be-

ingin immediate.i frictional contact there with. V

In using the device the roller. As shown in Figs. 5 and; 6 .the

blade holder will be actuated: by the alternateopposite.rotation-of said roller to throw the edge of said bladeinto'conta'ct with that portion of the strop which is moving out frontwardly from the frame. holder being held in inclined position with relation: to the strep, the preferred. heel to The blade point stropping efl'ect will beproduced, the

blade holder being returned to the interme-gj diate or-neutral position by the operationof V the spring ends 29 as soon as'the forward movement of the strop. has-discontinued, thus eifectually' preventing anycutting ofthe strop by backward movement: thereof against the harpedge'ofjthe blade I -It should be noted that the upper side pieces 6 and the lower side'pieces 9, adjacent their forward ends are provided with integral guide-roller-attachingportions:.38 bent out of the plane ofv the upper and lower frame plates and into. position at right-' angles to the line of inclination of theblade:

holder. Extending from. each upper side 9 piece to' the corresponding lower side piece and journaled 'in apertures in the portions 38 are the side,:rotatable, guide rollers39, so

arranged as'to engage the outer side of'tlie" strop in lines substantially corresponding to the lines of contact between the edge. of: the

razor blade and the inner side of the strop.

The upper front piece 7 and lower front" piece 10 are also bent out of the planes of 1 the upper and lower frame plates 1F and-2 respectively 3 said pieces? and 10 :lying; in planes paral tions 38. Intermediate the bars 11 and journaled in the upper and lowers-front pieces is the rotatable guide roller/1O adapted to coact with said bars '11- in maintainin the strop in proper position with-'nathe irame' and preventing the strop from contactingv withthe sharp edge of the razor blade when samelis in the neutral position.

It will, of course, be understood that the razor blade is inserted into the holder from the top end thereof, the said blade being pushed down until it engages the stop lug 1S, whereupon the springs 26 and 27, together with the flanges l5 and 16 will hold said blade firmly in position for the accurate stropping thereof.
